Principal Software Engineer, Core Infrastructure

At Oracle Cloud Infrastructure (OCI), we are building the future of cloud for enterprises. We combine the speed, ownership, and innovation mindset of a start-up with the scale, security, and customer focus of one of the world’s leading enterprise technology companies.

OCI provides the opportunity to build and operate large-scale, highly available cloud services in a globally distributed, multi-tenant environment. Our services power mission-critical workloads for customers tackling some of the world’s most complex business and technology challenges. Engineers at OCI have deep technical ownership and broad business impact, designing and operating systems that form the foundation of modern cloud infrastructure.

Our team owns one of OCI’s foundational control-plane storage services. The service provides a strongly consistent, highly available, transactional key-value store used by OCI services to persist and manage critical control-plane metadata. It is a tier-0 platform service that supports core OCI services across regions and realms, with strict transaction semantics, predictable performance goals, scalable data-plane architecture, streaming, garbage collection, cost-based throttling, and ongoing evolution of its storage and data models. The team’s mission is to simplify how OCI service teams build reliable control planes by abstracting database complexity while enforcing safe, consistent, and scalable access patterns.

We are looking for hands-on, senior technical leaders with deep expertise and passion for distributed systems, databases, storage infrastructure, transaction processing, and highly available services. As a Software Engineer on this team, you will help define and build the next generation of OCI control-plane storage. You will work on challenging problems such as read/write scalability, strict serializability, multi-version concurrency control, data-plane architecture, operational automation, performance isolation, resiliency, and global service growth.This is an opportunity to influence the architecture of a critical OCI platform service, mentor engineers, drive large technical initiatives, and build systems that directly impact the reliability and scalability of Oracle Cloud. The team is growing, the technical challenges are deep, and the work is central to OCI’s ability to operate cloud services safely at massive scale.

• Lead the design and evolution of foundational cloud infrastructure services that manage critical control-plane metadata and state for large-scale OCI services.
• Architect and build highly available, strongly consistent, low-latency distributed systems with a focus on correctness, durability, scalability, and operational excellence.
• Drive major technical initiatives across the full lifecycle, from architecture and implementation to safe rollout, production operations, and continuous improvement.
• Improve service scalability, performance, and predictability through better data-plane architecture, transaction processing, caching, throttling, capacity planning, and failure recovery.
• Build and operate resilient multi-tenant systems with strong observability, automation, alarms, dashboards, deployment safety, and incident prevention mechanisms.
• Mentor engineers, raise the engineering bar through design and code reviews, and establish best practices for distributed systems, production readiness, and operational excellence.
